Solution Overview & Operational Bottleneck
A bespoke business operations platform engineered for growing companies, trading firms, and multi-department enterprises. Replaces disconnected spreadsheets with deterministic state machines for quotations, purchase orders, inventory, and payroll.
Sales uses one spreadsheet, procurement uses another, and accounts reconciles invoices manually. Customer records are duplicated across four teams, approval limits are bypassed in email chains, and departing sales reps export client lists without authorization.
Target User Personas & Responsibilities
Managing Director / CEO
Requires real-time executive dashboard of cash flow, pipeline, and inventory margin.
Sales & Business Development Lead
Needs clean pipeline tracking, quick quote creation, and client interaction history.
Operations & Inventory Manager
Tracks purchase orders, goods receipts, and minimum stock alerts.
Finance & HR Controller
Enforces purchase approval limits, expense verifications, and payroll records.
